I want to trade for a copy of Contra for the NES

I have a CIB Dragon Warrior, Kirby's Adventure, Metroid, Robin Hood, Tetris and lots of other NES games. If you have an extra Contra cart or multicart that has contra or river city ransom on it let me know.

I also have a bunch of Sega games, Atari 2600 consoles and carts, and Original gameboy games as well.
